The document discusses a field trip to study coastal management techniques along the Hampshire and Dorset coastline in England. It provides information about the different defenses used at Highcliffe in Dorset, including groynes, beach replenishment, and cliff stabilization, and the natural rock armor and cliff stabilization used at Barton-on-Sea in Hampshire. The document notes that the two local councils disagree on coastal management strategies, with Highcliffe strongly protecting developed coastline including a golf course and housing, while Barton uses a managed retreat approach as it only contains farmland.

1. Field trip follow-up

2. What was learnt on the
field trip?
Did anyone get any pictures?

3. Booklets
Please copy over the notes/sketches on
management types
Then cut out and glue in your answers to the
questionnaire and your field sketches
Finally, please annotate your maps to show how
the land is used (use evidence + your memory) and
what coast defences there are

7. Barton-On-Sea & Highcliffe
Hampshire/Dorset coastline
The geology is very soft.
The cliffs are layers of sand and clay – very soft
rocks, unresistant to erosion.
Water from rain soaks in and makes the coastal
erosion worse by allowing material to slip and
collapse.

8. Barton-On-Sea & Highcliffe
Beach management is a political issue
Highcliffe is in Dorset, Barton in Hampshire
The two councils do not agree about coastal
management
What one council does to protect its coast, has a
big impact on the other coastline – e.g. Groynes
trap sediment which starves beaches downcoast,
meaning they are more vulnerable to erosion

15. What defences are there?
Make notes on Highcliffe vs Barton defences

22. Same problem, two places,
two different solutions
Highcliffe and Barton coasts are managed
differently: one is protected strongly, the other
is managed retreat
What do you think influences the decision makers
who decide how to protect coastlines?

23. What has happened here? Why?What has happened here? Why? What is this? Why has it been built?
How does it work?
Land use here:This is the border between Hampshire and
Dorset. Why is that important?:

24. How do they decide?
It all comes down to land-use, the value of the
land that needs protecting
Decision makers weigh up the costs of coastal
management, against the benefits of protection.
But each area is only responsible for itself, they
do not interact to see if they are affecting
another coastline

27. Barton side.
No defences.
No houses, just Naish
Farm camp site.
Cliffs are retreating inland by
several metres a year.

28. Highcliffe side.
Golf course and housing on the
cliff top.
Beach defences visible.
